Fruit And Vegetable Fresh-keeping Bags

The safety of food bags is always our primary concern. All our products are made of materials that meet national food safety standards, such as food-grade plastics, aluminum foil, kraft paper, etc., to ensure that they are non-toxic, harmless, and will not pollute food. We strictly abide by the relevant regulations of the food industry, select certified environmentally friendly materials, eliminate the infiltration of harmful substances, and ensure that consumers will not be harmed by any chemicals when they come into contact with food. In addition, we use clean workshops in the production process to strictly control microorganisms and harmful substances in the environment to avoid any possible secondary pollution. All finished products will undergo multiple tests, including heavy metals, solvent residues and other items, to ensure that they fully comply with international and national food safety standards.

Leakage resistance is one of the important considerations in the design of vacuum seal bags, especially for liquid foods or foods with high water content. We use special sealing technology at the bag mouth and edges to ensure that the bag still has an excellent sealing effect after multiple openings and closings. For example, the design with a zipper seal can provide multiple repeated sealing functions, which is not only easy to open, but also ensures the bag's long-term leak-proof performance. Our leak-proof design has passed professional testing to ensure that there will be no leakage during transportation and storage, thereby protecting the integrity of the food. In addition, we also use ultrasonic heat sealing technology at the seams of the food bag to increase the strength and toughness of the bag body, prevent accidental breakage and leakage, and ensure the safety of food during transportation.

Oxygen barrier properties are essential for the preservation of food, especially some oxygen-sensitive foods such as nuts, tea, coffee beans, etc. Oxygen entering the package may cause oxidation and deterioration of food, thereby affecting the taste and nutritional content of the food. To meet this challenge, we introduced multiple layers of barrier materials in the insulated lunch bag, which have extremely low oxygen permeability, thereby effectively extending the shelf life of the food. Our oxygen barrier materials include aluminum foil layers, aluminized film layers, etc., which not only effectively block oxygen, but also prevent light damage to food. In addition, our bags have been tested for high barrier properties and can effectively block the entry of oxygen while ensuring that the aroma and taste of the food are not affected. Through this efficient oxygen barrier design, our food bags can help food remain fresh and delicious after long-term storage.
